Hi All
I am calculating lattice parameters at various temperatures for HCP crystal using MEAM potential . I am using NPT and dumping lx,ly,lz to calculate lattice paramters .Although I see increase in lattice parameters with temperatures.My c/a ratio is constant at all temperatures and there is no anistropy thermal expansion seen for HCP crystal ?
